PUSl-ln-BUTTON SWITCH.

SPECIFICATION torming part of Letters Patent No. 690,946, dated January 14, 1902.

Application filed September 23, 1901. Serial No. 76,203. (No model.)

To all whom it may concern:

Beit known that I, MONROE GUETT, a citizen ofthe United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Push-Button Switches, of which the following is a specification.

This invention relates to an electric snapswitch that is operated by means of push-butio tons for opening and closing the circuit.

The object of the invention is the production of a compact switch of this nature that can be manufactured cheaply, that operates easily, smoothly, and rapidly, and that will i5 be durable and efficient.

This switch may be made either single or double pole for one, two, or more wires, the switch that is illustrated in the accompanying drawings as embodying the invention beeo ing a double-pole two-wire switch.

Figure 1 of the drawings is a side view of this switch with a portion of the receptacle cut away to expose the mechanisms. Fig. 2 is a similar View of the opposite side. Fig.

3 is a view, on an enlarged scale, of one side of the supporting, locking, and latch plates. Fig. 4 is a similar view of the other side of these parts. Fig. 5 is a view of a part of the supporting-plate and the latch and latch- 3o plate. Fig. 6 is a view of a part of the locking-plate and the latch, and Fig. 7 is a sectional view on linexoc of Fig. 2 looking as indicated by the arrows.

The receptacle 1 for containing the mechanisms maybe made of porcelain or any other suitable material. The wire terminals 2, 3, et, and 5 are provided with ordinary bindingscrews and pole-contacts and are secured in the receptacle in any suitable manner. A

4o frame-plate G is attached to the receptacle across one end, and secured to and projecting from the frame-plate is the rigid plate 7, that supports the mechanisms. The lockingplate 8 is pivotally mounted upon a spindle 4 5 9, that is held by the supporting-plate. Pushbuttons 10, which project through the frameplate, are connected by strips 1l with the locking-plate on opposite sides of the spindie, so that pushing the buttons oscillates the ,ends l5 and 16 ol' the spring 17, that is coiled about the hub oi the locking-plate, Figs. 3

and 4. vWhen the locking-plate is oscillated 6o in one direction, its lug engages an end of the spring and puts the spring under tension, and when the locking-plate is oscillated in the opposite direction the lug engages with the othereud of the spring and puts the spring under tension oppositely. The latch-plate 18 is pivotally mounted upon the spindle. This latch-plate has a lug 19, that extends between the ends of the spring outside of the lug on the locking-plate, so that when the 7o spring is made tense by the movement of the locking-plate lug against one end the other end of the spring tends to throw the latchplate, Figs. 3 and 1l. Pivoted to the latchplate is a latch 20. The latch has a round hub 21, that projects into the opening 22 in the supporting-plate. At the end of this hub is a triangular stud 23, that projects into the opening through the locking-plate adjacent to the curved wall of that opening, Figs. 3 8o and 4. As the center ofthe hubof the latchthat is, in the opening in the supportingplateis but slightly farther out from the axis of the latch-plate than the center of the pivotal connection between the latch and the S 5 latch-plate, the latter is locked against being thrown over` by the engagement of the hub with the Walls of the opening until the hub of the latch can move out radially of the latchplate along the opening in the supporting- 9o plate, Fig. 5. The hub cannot thus move as long as the latch-stud is confronted by the curved wall of the opening through the locking-plate, Fig. 6. When the locking-plate is moved by pressure upon the outer push-button and its lug places the spring under tension by engaging With one end, the latchplate and its lug that is engaged by the other end of the spring cannot move until after the locking-plate has been moved so far that one of the radial openings in the locking-plate comesoppositethelatch-stud. Then thelatchstud, being unobstructed, permits the hub to move outwardly in the opening in the sup` porting-plate, so that the force of the spring can throw the latch-plate to the opposite side. The curved locking-wall is of such length that the spring is placed under sufficient tension to quickly throw the latch-plate when the radial slot is opposite the latch-stud, so that the latch can swing outwardly and then inwardly to its normal position in the opening in the supporting-plate as the latch-plate is thrown over. The radial slots are so arranged that it is necessary to push in a button and move the locking-plate slightly farther than its normal position before it will release the latch, and when the pressure is removed from the button the spring will move the locking-plate backward until the latchstud is opposite the end of the curved wall of the opening through the locking-plate, from which position the latch cannot move outwardly until after the locking-plate has been oscillated to the opposite side.

The poles 2-1 and 25 project from an insulated plate on the spindle near one end and that is connected with the latch-plate, so as to be thrown into and out of engagement with pole-contacts as the latch-plate is oscillated, Fig. 2. The poles 26 and 27 project from an insulated plate on the spindle near the other end, which plate is connected with the latchplate by the lug that projects from the latchplate between the ends of the spring, so that these poles are oscillated into and out of engagement with pole-contacts as the latchplate is oscillated, Fig. l. Ot' course either or both of the poles on either side could be omitted, if desired.

There is no complicated mechanism in this switch to wear out, and all the pieces may be stamped to shape and quickly assembled into a compact structure. There is but little friction, so that the movements are easy, and the action is quick, so that the switch is efficient.
